PLEASE HELP ASAP!!!!!! 1. Why do you think the military breaks complex technical jobs, like space shuttle navigation, into smaller specialties? Do you agree with this practice?2. Using a communications system as an example, describe the various careers that might be involved and their interplay amongst each other. Your answer should name at least three careers/job categories, but you dont have to name them explicitly. In your answer, explain why you think its important that each person performs their job correctly.3. What were two of the greater challenges faced when using early satellite imaging, compared to modern systems? What do you think we can do now with satellite imaging that we couldnt do previously?4. Why do you think public affairs professionals are used or consulted when a newsworthy event happens, instead of just having a regular officer talk about an issue? 5. What do you think Chaplain Tanya Bindernagel meant when she discussed a ministry of presence? What is your opinion about the way she chooses to share her faith?6. What is the point of having dedicated military bands? Do you think their cost (in terms of payroll, travel, and maintenance) is a worthy investment for the military? Why or why not?7. What are the advantages of the Navys two medical ships compared to standard hospitals? Why would these differences be important?8. Whats one major advantage of working for the military as a medical researcher? If you chose to become a medical researcher, do you think it would be a good option to work for the military? Why or why not?
8. 15 A manual arc welding cell uses a welder and a fitter. The cell operates 2,000 hriyr. The welder is paid $30/hr and the fitter is paid $25/hr. Both rates include applicable overheads. The cycle time to complete one welded assembly is 15. 4 min. Of this time, the arc-on time is 25%, and the fitter's participation in the cycle is 30% of the cycle time. A robotic arc welding cell is being considered to replace this manual cell. The new cell would have one robot, one fitter, and two workstations, so that while the robot is working at the first sta tion, the fitter is unloading the other station and loading it with new components. The fitter's rate would remain at $25/hr. For the new cell, the production rate would be eight welded assemblies per hour. The arc-on time would increase to almost 52%, and the fitter's participation in the cycle would be about 62%. The installed cost of the robot and worksta tions is $158,000. Power and other utilities to operate the robot and arc welding equipment will be $3. 80/hr, and annual maintenance costs are $3,500. Given a 3-year service life, 15% rate of return, and no salvage value, (a) determine the annual quantity of welded assem blies that would have to be produced to reach the break-even point for the two methods. (b) What is the annual quantity of welded assemblies produced by the two methods work. Ing 2,000 hryr?
